Hexyldecanol

What is Hexyldecanol?

Hexyldecanol is a branched-chain primary fatty alcohol featuring a 16-carbon chain, often synthesized from natural fats or petrochemicals. It falls into the emollient and multifunctional excipient category in cosmetics, appearing in moisturizers, sunscreens, cleansers, and hair care products. Chemically, its structure provides a non-greasy, velvety feel by aligning with skin lipids to fill surface imperfections and create a breathable barrier. As a solvent, it evenly disperses oils and actives, controlling thickness and aiding penetration without residue. Its humectant action binds water molecules near the skin surface, while skin conditioning effects promote flexibility and suppleness. This ingredient boosts formula stability, spreadability, and sensory appeal, making products easier to apply and more comfortable on diverse skin types.
